3 Claims. i

This` invention relates to a sink frame.V and more particularly to asink frame incorporating means for mounting a, sink in engagement therewith. v l

The principal object of the invention is the provision of a sink frame and means for mounting a sink in engagement therewith.

A further object of the invention is the provision of a simple and inexpensive sink frame mounting which may be used in securing a sink in a cabinet construction.

A still further object of the invention is the provision of a sink frame and mounting which may be formed of extruded metal sections and applied to various cabinet constructions for the purpose of supporting sinks therein.

A still further object of the invention is the provision of a sink frame and mounting incorporating definite structural advantages over the sink frames and mountings heretofore known in the art.v

The sink frame and mounting therefor disclosed herein comprises an improvement in the art of mounting sinks and more particularly sink bowls in counters or sink tops such as is customary in the art wherein a water-tight seal is desired between the sink bowl and the surface material of the counter or sink top and wherein the sink bowl is supported by the counter or sink top. It isA known that various constructions have been proposed for mounting sink bowls in openings in the sink tops or counters and it is also known that a majority of these proposed constructions have been unsatisfactory in use primarily due to the mechanical difliculties encountered in mounting sinks with the proposed constructions and a further disadvantage of the failure of the constructions once the sink bowl is mounted therein.

The present invention comprises an improvement in this art and particularly with Yrespect to my co-pending application Serial No. 95,183 on Sink Frame and Mounting and in which a sink frame and mounting is disclosed wherein the bolts having key-shaped heads are engaged in a dovetailed slot in the sink frame and the sink bowl suspended therefrom and which construction in actual practice has been found to be objectionable in that undue mechanical pressure applied to the bolt and nut results in ypulling the same from its normal positioning in the frame. Additionally, a sink frame of heavy cross section is necessary to provide the dovetailed channel for the reception of the key-headed bolts. These objections are overcome and eliminated in Y the construction as disclosed herein wherein the of another extruded shape may be engaged so as to be suspended therefrom and usable in supporting a threaded bolt which in turn engages the sink bowl and supports the same against the frame. The construction in this application is, therefore, simpler in formation and incapable of being rendered inoperable. Y

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a perspective view with parts in cross section and parts broken away illustrating the sin'k frame and mounting holding a sink bowl in a counter top.

Figure 2 is a perspective view of a section of the sink frame shown in Figure 1.

Figure 3 is a perspective view of one of the levers used with the sink frame and mounting shown in Figure 1.

By referring to the drawings and Figure 1 in particular it will be seen that a counter top I0 has an opening Il therein for the reception of a sink bowl I2 which is outwardly flanged and the flange indicated by the numeral I3. The top I0 is provided with desirable lsurfacing materia1 I4 such as linoleum. In order that the sink bowl I2 may be positioned in the opening l I in the top` Il] and in approximately ush registry with the top thereof, a sink frame I5 is positioned in the opening II and around the outer edge of the flange I3 of the sink bowl I2.

The frame I5 comprises a horizontal ange overlying the surfacing material lli on the top I and overlying the flange i3 of the sink bowl I2 and also rincludes a depending flange I5A which is provided at intervals therealong with a plurality of longitudinally spaced staggered slots !6-I5. The staggered slots IG-l are formed on two different vertical planes with respect to the normally vertical depending ange IEA of the frame I5. The lowermost row of slots Iii-I6 lies near the lower portion of the flange IEA and the upper row lies approximately midway between the upper and lower edges of the flange IEA. Both rows of the slots l-I are formed on a transverse angle in the depending ange iEA as best shown in Figures l and 2 of the drawings, the transverse angle of their formation being upwardly and inwardly toward the portion of the frame I that normally overlies the ange I3 of the sink I2. This portion of the frame I5 is slightly thicker than the corresponding or oppositely disposed portion and is indicated in the drawings by the numeral iB. lt will be observed that it isV slightly undercut so that a feather edge is formed with respect to the upper surface of the ange I3 on the sink bowl I2 where the same is engaged by the frame The plurality of longitudinally spacedY slots Iii-I enables cut sections Il or" an extruded shape to be engaged on the frame I5 and, as illustrated in Figure l ofthe drawings, these cut sections I7 forni levers, each of which has an upstanding hook-like section HA which is engaged in one of the slots It. as heretofore described. Each of the cut sections ll also has an outwardly extending and upturned end i8 which is adapted to engage beneath the top Ill, as best shown in Figure l of the drawings, and each of the cut sections. Il has an oppositely disposed outwardly extending section I9 which has a vertical drilled and tapped opening 2t therein. A bolt 2l is threadably. engaged in the opening 2t in inverted position so that the head or the bolt is below the extension I9 and the end of the bolt 2E is above the extension I9 and capable of being moved upwardly when the bolt 2i is rotated into engagement beneath the flange i3 of the sini; I2 at a point corresponding approximately with the outer edge of the portion |535 of the frame I5.

It will thus be seen that the sink frame and mounting comprises two metal shapes as shown in Figures 2 and 3 of the drawings and that both of these shapes may be easily formed as extrusions of desirable metal such a aluminum.l The extrusion, comprising the frame I5 has the plurality of longitudinally spaced angularly disposed slots I5 form-ed therein and the cut sections Il comprising a relatively short section of an extrusion of the indicated cross section with the opening 2d drilled and tapped in the extension E9 thereof. The bolts 2l are ordinary bolts having heads either squared forY engagement with a wrench or with a transverse slot as shown in Figure l in which a screwdriver may be engaged for rotating the same.

ln operation the opening II in the counter top Ill is formed to be slightly larger than the over-all size of the flanged sink bowl I2 and the frame I5 is positioned in the opening sothat the outer edge of the top ange thereof registers over the counter top Iii and the surfacing material Il thereon. The sink bowl I2 is then positioned in the opening by moving the same upwardly therein into engagement with the flange IB of the frame and a plurality of the cut sections I l are engaged in the slots I-I at spaced intervals along the fram-e I5 and the bolts El positioned in the openings 2G therein and moved upwardly into engagement beneath the fdange I3 cf the sink bowl I2. This action serves to tilt the cut section I'I slightly, which section forms a supporting bracket and causes the outwardly and upwardly curved end I8 thereof to engage beneath the counter top I as the cut sections CJI 4 Il fulcrum on the upwardly formed hook section I'a'A.

When the bolts 2I are rotated to bring them into tight engagement with the flange I3, the same is moved upwardly against the portion I5B of the frame I5 and a tight and structurally strong sink mounting is realized. It will occur to those skilled in the art that water-proof cements may be applied beneath the frame I5 to insure a water-tight seal if desired. It will also occur to those skilled in the art that considerable tension is created between the sink ange I3 and the frame I5 and particularly the ilange ISB thereof so that a desirable seal is Obtained. It

will also occur to those skilled in the art that thestaggered slots iS-V I 6 enable the device to be used with sink tops of varying thicknesses, as in the case of a relatively thinner sink top IU the hooks il may be engaged in one of the slots It lying closer to the top. of the frame I5. The sink ange and framing mounting` is thus capable ofbeing used with any thickness of counter top or cabinet construction as well as with any thickness of flange on the sink bowl. rIfheY weight of the sink bowl is carried on theheavy vertical depending ange 55A or` the frame I5 which easily carries the weight and is incapable or being broken by too great tension exertedbi7 the bolt 2 I.

rfhe construction overcomes the principal disadvantages of the severalv constructions heretofore known in the art and at the same time provides an extremely simple and inexpensive sink frame mounting meeting the several objects ofthe invention.

Having thus described my invention, what I claim is:
